Abstract
The present invention employs a statistical multiplexing method to enable suitable assignment of a target code rate to each program data. A controller () acquires encoding difficulty (Di) of each program from each of image encoders (). In accordance with an equation for transforming the encoding difficulty (Di) into a bit rate, the controller () calculates a temporary bit rate (Tmp_Ratei). Moreover, the controller () causes the sum of the target bit rates (Target_Ratei) to satisfy a predetermined allowable value by correcting the temporary bit rate (Tmp_Ratei) so as to determine a final target bit rate (Target_Ratei) and inputing the final target bit rate (Target_Ratei) to each of the image encoders ().
